Uhmm whitespaces in filenames, now what was it about the IFS....

I had to rename som digital images, so startet to write a simpel for-loop in bash, but uhmmm ..... oh no I foregot that those whitespaces needs special attention. I googl'et it and found the needed help linuxquestions and of course also in The Advanced Bash-Scripting Guide

It ended something like this:

IFS=$'\n'
for filename in $(ls *.jpg)
do
 subFilename=$(echo $filename | cut -d' ' -f3)
 mv $filename [myNewPrefix]-$subFilename
done

And now I'll hopefully remember it - at least I'll be able to find it here.
